Product Overview

The 1734-IE8CK is a high-density input module engineered by Allen-Bradley for the POINT I/O 1734 series. Designed for precision data acquisition, it features eight single-ended, non-isolated current inputs supporting 0 to 20 mA and 4 to 20 mA ranges. Built with an integrated conformal coating for enhanced durability in harsh industrial environments, the module utilizes a delta-sigma conversion type with 16-bit resolution. Weighing approximately 0.15 kg, it delivers signed integer data format with 0.1% full-scale accuracy at 77°F, protecting against overloads up to 28.8 V DC.

Core Technical Advantages

  • High-Density 8-Channel Design: Provides eight current input channels in a compact POINT I/O module footprint.
  • Conformal Coating Protection: Factory-applied protective coating shields circuitry from corrosive industrial elements.
  • Precise Delta-Sigma Conversion: 16-bit resolution delivers accurate measurements across 0–20 mA and 4–20 mA current loops.
